| Comments | Polycyclic aromatic hydrocarbons (PAH) are a class of chemicals, consisting of hydrocarbons with at least two connected aromatic ring systems. They may be produced during the processing of foodstuffs, such as smoking. They may, however, also find their way into foodstuffs unintentionally, e.g. from mineral oils. Because they may have negative effects on health – they are associated with cancer and other diseases – threshold values have been set for PAHs. Accurate analyses regarding these chemicals are therefore called for. There were other comparisons previously conducted for the determination of PAHs. CCQM conducted key comparisons with final reports published in 2018 (CCQM-K95.1: Polycyclic Aromatic Hydrocarbons (PAHs) in Tea) and 2020 (CCQM-K146: Benzo[a]pyrene in Olive Oil). So far, however, no comparison of PAHs in a protein-rich matrix has been carried out. In this comparison the target PAHs are benz(a)anthracene (BaA), benzo(a)pyrene (BaP), benzo(b)fluoranthene (BbF), and chrysene (Chr) in a protein-rich matrix. Successful participation in this supplementary comparison will demonstrate the measurement capabilities in determining mass fractions of low polarity organic compounds with molecular masses of about 150 - 500 g/mol in the mass fraction range from 0.1 µg/kg to 100 µg/kg (as received) in a protein-rich matrix. |
